Advancing The Particle-Scale Understanding Of Atmospheric Aerosol

Session ID#: 78085

Session Description:
Atmospheric aerosol particles influence environmental health and climate change. State of the art measurements and modeling are key tools for investigating aerosol processes such as ice and liquid cloud formation, nucleation, chemical and photochemical aging, secondary organic aerosol formation, radical generation, optical properties and phase state. This session welcomes submissions aimed at improving the understanding of aerosol processes at the particle-scale, which is imperative for predictive understanding of aerosol effects on climate and human health. This session will include studies utilizing single-particle analysis, micro-spectroscopy, mass spectrometry and other experimental investigations. In addition, global, regional, and parcel model studies are invited to elucidate atmospheric links with physics and chemistry on a per-particle scale. This session aims to improve our fundamental insight and better representation of atmospheric aerosol.
